Wondering why Cetirizine is hard to find? Learn about seasonal stock-outs, supply chain issues, and how to get Zyrtec or generic Cetirizine in 2026.
If you've been to your local pharmacy recently and found the Cetirizine shelf empty, you're not alone. Cetirizine — sold under the brand name Zyrtec and many store-brand generics — is one of the most popular over-the-counter (OTC) allergy medications in the United States. Millions of people rely on it daily for relief from seasonal allergies, year-round allergic rhinitis, and chronic hives (urticaria).
While Cetirizine is not currently listed on the FDA's official drug shortage list, many patients have reported difficulty finding it on pharmacy shelves — especially during peak allergy seasons in the spring and fall. Let's break down why this happens and what you can do about it.
The most common reason Cetirizine becomes hard to find is simple supply and demand. During spring allergy season (March through June) and fall ragweed season (August through October), demand for antihistamines surges dramatically. Pharmacies and retailers may not stock enough to keep up with the rush, leading to temporary empty shelves.
This is especially true for popular store-brand generics — like Costco's Kirkland Aller-Tec or Walmart's Equate All Day Allergy — which offer significant savings and tend to sell out first.
Since the COVID-19 pandemic, global supply chains for pharmaceutical ingredients and consumer health products have faced ongoing disruptions. While Cetirizine is manufactured by many companies (making a true nationwide shortage unlikely), localized supply issues can still occur due to:
These factors can create a patchwork of availability — where one pharmacy is out of stock while another a few miles away has plenty on the shelf.
Brand-name Zyrtec (made by Johnson & Johnson) is generally well-stocked but costs significantly more than generics. If you're specifically looking for a store-brand generic, you may find that particular product out of stock even when brand-name Zyrtec is available — or vice versa.
The good news is that all Cetirizine products contain the same active ingredient. A 10 mg tablet of generic Cetirizine works exactly the same as a 10 mg Zyrtec tablet. If your usual brand is unavailable, any Cetirizine product is an equivalent substitute.
Most people buy Cetirizine over the counter, but there are prescription-only formulations:
If you need one of these prescription forms, availability depends on your pharmacy's supplier and may be more limited than the standard oral tablets and liquids.
If you're struggling to find Cetirizine, here are some practical steps:

If Cetirizine is consistently hard to find in your area, you might consider switching to another second-generation antihistamine. The most common alternatives include:
All of these are available over the counter and treat the same conditions. Talk to your doctor or pharmacist about which one might work best for you. For a deeper comparison, see our post on alternatives to Cetirizine.
Cetirizine is not in a formal nationwide shortage, but seasonal demand spikes and localized supply chain issues can make it temporarily hard to find. The best strategies are to plan ahead, buy in bulk when possible, use tools like MedFinder to check availability, and be flexible about which brand or form you purchase.
